DISK PLOW.

SPECIFICATION forming part of Letters Patent No. 738,818, datedSeptember 15, 1903.

, Application filed June 16, 1903. Serial No. 161,588. (No model.) i

To aZZ whom it may concern.-

Be it known that I, HUGH M. KING, a citizen of the United States,residing at Oklaunion, in the county of Wilbarger and State of Texas,have invented a new and useful Disk Plow, of which the following is aspecifica tion.

This invention relates to gang disk plows of that class in which aplurality of dished disks are mounted upon a single shaft or axle whichmay be set at various inclinations to the line of draft for the purposeof regulating the depth of the cut into the soil.

My present invention has for its object to provide a disk plow of thisclass in which all tendency to side draft shall be obviated, this beingone of the serious objections in the use of this class of plows, whichwhen set to penetrate deeply into the soil offer a resistance to thedraft which usually results in their being thrown out of line.

A further object of my invention is to provide means whereby the gang ofplows may be set in such a manner as to cause the inner and outermembers of the gang to cut into the soil to an equal depth. Under usualcircumstances the inner disks-that is, those nearest the line of draft--are apt to cut more deeply than the outer ones. By my invention I aimto so adjust the shaft carrying the disks that this objection shall beovercome, the plows at the outer end being simply set more deeply thanthose at the inner end, so that any tendency of the inner plows to cutmore deeply shall be compensated for and equalized.

With these and other objects in view, all tending toward the productionof a device of the class described which shall possess superioradvantages in point of simplicity, durability, and general efficiency,my invention consists in the improved construction, arrangement, andcombination of parts, which will be hereinafter fully described, andparticularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a top plan view of a gang diskplow constructed in accordance with the principles of my invention. Fig.2 is a side elevation of the same. Fig. 3 is a rear elevation. Fig. 1

is a sectional view taken on the line 4c 4 in Fig. 3. Fig. 5 is asectional detail view taken on the line 5 5 in Fig. 1.

Corresponding parts in the several figures are indicated by similarnumerals of reference.

I desire it to be understood at the outset that my invention isapplicable to disk gangplows having any number of disks. In theembodiment of the invention illustrated in the drawings hereto annexed Ihave shown a plow provided with three cutting-disks, this being known asa. three-gang plow. The three flat disks appearing at one side of thedevice are known as the steering-disks, as will be presently more fullydescribed.

1 designates the tongue, upon the rear end of which is mounted a seat 2,the standard or support 3 of which is pierced by a bolt 4., whichextends through the tongue 1 and serves for the attachment to the underside of the latter of a pair of plates 5 and 6. These plates which arethus pivota ly connected with the tongue are each provided with anupwardly-extending sleeve 7, through which extends a bolt 8. To thesleeves 7' are attached a pair of forwardly-converging braces 9 and 10,the front ends of which are provided with T-heads 11, Working in slots12 in the sides of keepers 13, secured upon the op posite sides of thetongue or beam. Thelatter is provided with oppositely-disposedhandlevers 14 and 15, fulcrumed on opposite sides thereof and providedwith suitably-operated lock-dogs 16, adapted to engage toothed quadrants17, connected with the tongue. These levers are connected by means oflinks 18 with the T-heads 11 on the respective braces 9 and 10, whichmay thus be manipulated so as to set the pivoted plates 6 and 7 at anydesired angle or inclination to the tongue or beam.

One of the plates, in the present instance the plate 6, is provided onits under side with downwardly-extending curved brackets 19, carryingboxes 20, which serve to sustain a shaft 21, upon which a plurality ofdished disks 22 are mounted. In the present example three such diskshave been shown, the outer sides of said disks being concave and theconcavo-convexity of said disks corresponding with the curves of thesupportingupon the opposite brace 9.

brackets 19. This is for the purpose of preventing the disks fromengaging the .said. brackets frictionally, which in the absence of thisspecial construction might be possible. The opposite plate 7 is providedwith straight downwardly-extending brackets 23, supporting boxes 24, inwhich is journaleda shaft 25, carrying aplurality of flat disks 26,which I call the steering-disks.

The boxes 20 and 24 may be constructed of wood and are held clamped bythe supporting-brackets 19 and 23, which are provided with seats 27, forsaid boxes and with flanges 28 and clamping-plates 29, connected bybolts 30, whereby the said boxes-may be tightened upon the shafts, eachof said boxes being composed oftwo members grooved for the reception ofthe respective shafts.

The brace 10 is pivotally connected with a transversely-disposed rod 30,which extends through a perforation 31 in a lug 32, formed It will thusbe seen that by means of the braces 9 and 10 and the rod 30 the plates 6and 7, carrying the disks, are suitably connected in any position towhich they may be adjusted.

The operation of my invention will be readily understood. It will beseen that by means of the operating-lever 16 the plate 6, carrying theplow-disks, may be set to any desired degree of inclination withreference to the line of draft, thereby causing the plowdisks to cutdeep or shallow, as may be desired. If the out is shallow, the platecarrying the flat guiding or steering disks 26 may he suffered to remainpractically at right angles to the line of draft, as indicated by thetongue. Should there be any tendency to side draft, this may becounteracted by properly adjusting the plate carrying the steering-disksat such an angle to the tongue 1 the dished plow-disks will becounteracted,

as the plow will be caused to progress steadily in a straight forwarddirection.

Any tendency on the'part of the inner plowdisks to cut more deeply intothe ground than the outer ones may be overcome by properly adjusting thebolt 8, extending through the sleeve 7 0f the plow-carrying plate 6 tolower the outer end of said plate, and thereby setting the outerdiskslower than the inner ones.- The extent of adjustment necessary to effectthe proper equalization of the depth of cutof each disk may be readilyascertained by experimenting, and will of course be to some extentgoverned by the condition of the soil in which the machine is operated.

My improved plow is useful in operating in all kinds andin allconditions of soil. If the latter is soft and loamy, the operation willnaturally be easy; but the excellent qualities of myimproved plow willbe best noted when it is applied to the cultivation of hard, baked, anddry soil, which is the usual condition of the soil in the semi-aridlocalities west of the Mississippi. In localities such as these andwhere large crops are invariably put in aplow that is useful for plowingonly in moist and mellow land is entirely useless. The soil in order toenable the crops to be put in must be cultivated no matter what may bethe condition thereof. Plows of ordinary construction will not operatesuccessfully in land that is. normally inthe dry condition referred toabove. It is true that they may be used occasionally; but they will notenable a man toput in the large acreage which under the circumstances ispracticable and necessary. I

have found, however, that by means of my ment with the soil of theplbw-disks and which by cutting straight into the soil will greatlyfacilitate the operation of said plow-disks and enable them to performthe work assigned to them in a most thorough and satisfactory manner.

I have in the foregoing described a simple and preferred construction ofmy invention; but I desire it to be understood that I do not limitmyself to the structural details of the same, but reserve the right toany changes, modifications, and alterations which may be resorted towithin the scope of my invention and without departing from the spiritor sacrificing the utility of the same.

Having thus described my invention, I claim 1.

2. In a gang disk plow, a supporting-plate, brackets extendingdownwardly from the same and provided with supporting seats and withclamping-plates, wooden boxings clamped and supported by said brackets,and a disk-carryin g shaft j ournaled in said boxes.
